vlowres —
A bank of filters in which the cutoff frequency can be separated under user control.

Description

A bank of filters in which the cutoff frequency can be separated under user control

Syntax

ares vlowres asig, kfco, kres, iord, ksep

Initialization

iord -- total number of filters (1 to 10)

Performance

asig -- input signal

kfco -- frequency cutoff (not in Hz)

kres -- resonance amount

ksep -- frequency cutoff separation for each filter: the first filter has a kfreq cutoff, the second has a kfreq + ksep and the third kfreq + 2*ksep and so on, depending on the number of filters.

vlowres (variable resonant lowpass filter) allows a variable response curve in resonant filters. It can be thought of as a bank of lowpass resonant filters, each with the same resonance, serially connected. The frequency cutoff of each filter can vary with the kcfo and ksep parameters.
